I would like to turn off enabled ADB over WiFi from inside ADB shell after executing a shell script before it. The main reason is that I simply want to start some script, and get rid of overhead caused by ADB over WiFi connection. I do need a WiFi connection itself, so adb shell "svc wifi disable" will not work.
Is there a way to control this development option remotely somehow without touching the screen?
Or possibly there is a am start command that could do this? Something like am start -n com.android... or am start -a android.intent.action...
adbd is the adb daemon that runs on your devices, awaiting connection.
issuing stop adbd should kill it - you may have to run this as root, should stop adb on the device, and disconnect your active shell.
edit
just tried this and it worked for me, running cyanogenmod. using adb connect <ip>, and entering an adb shell, su for super user privileges, and then issue stop adbd. your shell should terminate, and you will not be able to reconnect until you restart it from your device. (shell or settings menu)
